PU LSATING STEAvIVl-PUIVI P.

SPECIFIGATION forming part of Letters Patent No. 607,357, dated July 12, 1.898.

Application iiled September 29, 1896. Serial No. 607,327. (No model.) Patented in England July 3, 1895,1To. 12,806.

To all wwm/ it may concern:

Be it known that I, WILLIAM THOMAS EL- LIsO'N, a subject of the Queen of Great Britain, residing at Irlams-oth-I-Ieight, near Manchester, in the county of Lancaster, England, have invented new and useful Improvements in Pulsating Steam-Pumps, (for which British Patent No. 12,806, dated July 3, 1895, has been obtained,) of which the following is a specification.

My invention relates to the construction of pulsating steam-pumps for pumping all kinds of liquids, sewage, and the like, the object of my invention being to have a double-action pump in one cylindrical, conical, or other suitable vessel.

According to my said invention I form in a cylindrical, conical, or other suitablevessel a division-plate down its center, thus bisecting the circular or other section of the vessel into two parts of equal Yarea (the said divisionplate acting as a condenser, which, if required, can be provided with a few small holes in it) and terminating at the base, thus forming two valve-chambers, and I also connect the two steam-inlet apertures at the top bya ridge or cover at, say, an angle of vninety degrees to suit my purpose. By this means I can place a valve resting on the apex of the ridge formed by the aforesaid angle, the said valve thus being sensitive, as it has its center of gravity below the point of suspension. I also prefer to place or arrange the suction and delivery valves so that they shall both be horizontal.

In order that my invention may be clearly understood, I have annexed hereto a sheet of drawings, and have marked the same with letters of reference corresponding with those in the following description.

Figures l and 2 are front and side elevations in section through about the center of the pump made according to my invention. Fig. 3 is a plan view thereof, and Fig. l is a horizontal section taken through about the lines A B on Fig. 2. Figs. la and 2fL illustrate modifications hereinafter particularly referred to.

a is the vessel or body of the pump, divided by the plate or partition ai into the two valvechambers a' a2. The plate or partition a+ being a wall common to both chambers a' and Ca2 of the greatest possible area (being at' the center or broadest part of the vessel a) forms a very perfect condenser to create the vacuum necessary to raise the water into one of the cham bers, (say a,) which is filled with steam, while the other chamber (say a2) is filled with water or liquid fresh from the well or source of supply. The division-'plate a+ may be corrugated sheet metal or may be provided with radiating ribs or otherwise formed with increased condensing-surface.

b b2 are the suction-valves admitting the liquid from the inlet a3 to the valve-chambers a a2, respectively, and c o2 are the respective delivery-valves of the said chambers a a2, leading to the outlet CL4, and since, as before stated, I prefer to arrange the valves b' b2 0/ c2 horizontally it is evidently necessary that the vessel a must be enlarged at the lower end, as seen on the drawings, to allow of such construction.

Figs. l, 2, and 3 show the vessel c conical; but it may be cylindrical or of other suitable form, providing that the plate or partition a+ divides it into two chambers of equal size and extends from top to bottom of the said chambers. i

I may make a few holes in the divisionplate a+ to assist the formation of the vacuum, and these holes should be below the level of the delivery-valves c c2. I prefer, however, to make or form a short passage a5 in the center of the vessel a and to form in this passage holes at or near the top and bottom thereof, communicating with the chambers a a2. (See also sectional detached view, Fig. 2a.) By this means when the liquid is being forced down out of one chamber (say a) part will enter the short passage a5 through the lower hole a8 and will be injected through one of the upper holes into the second chamber (say a2.) Each of the upper holes leading from this passage into the chambers a a2 is or may be provided with a short pipe a6, which may be, if preferred, made or iitted with a rose a7. and 2.) This injection of liquid from one chamber to another assists the formation of the necessary vacuum and renders my pump very easy to start. rlhe top of the passage a5 is open to the space above the deliveryvalves c c2, so that the passage a5 can also IOO 1o ffl is suspended either as seen at Fig. 1 or at Fig. la. The said valve f f2 opens or closes the apertures e e2 alternately, as usual in pulsating steam-pumps, and being suspended, as described and shown, the valve f' t5 f2 is most sensitive and quick in action, as

its point of suspension is above its center of gravity and not below it, as is usual in angular or other valves for this purpose.

Thezvalve f f2 is inclosed, as usual, by a cover g, to which the usual steam-admission pipe may be connected at g. If preferred, the top of the vessel or may be made separate therefrom, as seen at Fig. l, and connected thereto by bolts or otherwise.

I claim as my inventionl. A pulsating steam-pump in the form of a single vessel provided with a vertical partition across its broadest part acting as a condenser and dividing the vessel into two compartments, the said vessel being provided with a passage a5 having openings 0,8 communicating with each compartment of the vessel, and pipes a6 leading from the said passage into the compartments, substantially as and for the purpose set forth.

2. A pulsating steanrpump in the form of a single vessel of suitable shape, provided with a vertical division-plate or partition extending from lside to side thereof at the broadest part of the vessel and having valveseats at the top thereof arranged atan angle of about ninety degrees to each other, thus forming a ridge, and a valve suspended on said ridge with its pointof suspension above its center of gravity, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
